style="text-indent:25px">油缸是工程機(jī)械主要部件，傳統(tǒng)的加工方法是拉削缸體--精鏜缸體--磨削缸體。采用滾壓方法是:拉削缸體--精鏜缸體--滾壓缸體，工序是3部分，但時(shí)間上對(duì)比:磨削缸體1米大概在1-2天的時(shí)間，滾壓缸體1米大概在10-30分鐘的時(shí)間。投入對(duì)比:磨床或絎磨機(jī)，滾壓刀。滾壓后，孔表面粗糙度由幢滾前Ra3.2~6.3um減小為Ra0.4~0.8&um，孔的表面硬度提高約百分之30，缸筒內(nèi)表面疲勞強(qiáng)度提高百分之25。油缸使用壽命若只考慮缸筒影響，提高2~3倍，鏜削滾壓工藝較磨削工藝效率提高3倍左右。以上數(shù)據(jù)說明，滾壓工藝是高.效的，能較大提高缸筒的表面質(zhì)量。油缸經(jīng)過滾壓后，湖州液壓系統(tǒng)怎么樣，表面沒有鋒利的微小刃口，湖州液壓系統(tǒng)怎么樣，湖州液壓系統(tǒng)怎么樣，長(zhǎng)時(shí)間的運(yùn)動(dòng)摩擦也不會(huì)損傷密封圈或密封件，這點(diǎn)在液壓行業(yè)特別重要。用兩個(gè)液控單向閥或一個(gè)雙單向液控單向閥實(shí)現(xiàn)液壓缸鎖緊的液壓系統(tǒng)中。湖州液壓系統(tǒng)怎么樣</p><div
